WALL CONSTRUCTION.

Application led April 1G, 1923. Serial No. 632,326.

To aZZ whom t may concer/n:

Be it known that I, FRANK B. ALLEN, a

citizen of the United States, residing at 4 separate lining units of new and improved configuration.

One object of the invention is to provide a metal wall unit or element having `means located on its exterior surface for engagement with securing means, such as bolts, thereby avoiding perforations through the unit for such securing means.

Another object is to provide a metal Wall unit or element having on its interior surface inclined flanges or projections adapted to support lining elements or units throughout a relatively wide range of inclination of the wall units with respect to the vertical.

Another object is the provision of a wall lining element or unit preferably composed of refractory material and of such a crosssectional configuration as will render it capable of being supported, without securing means, against dislodgement throughout a relatively wide range of angular inclination of the wall element with respect to the vertical.

A further object is to construct a wall lining unit having substantially equal rectangular sides and being rectangular in cross section with opposite included angles of approximately Further objects will appear and be pointed out hereinafter in the description of a practical embodiment of my invention.

In the drawing accompanying this application and forming a part thereof,

Fig. 1 is a fragmentary perspective view of an ash hopper constructed in accordance With my invention.

Fig. 2 is a side view in elevation of several wall units forming the wall of the hopper shown in Fig. l, as the units appear from the interior of the hopper.

Fig. 3 is a cross sectional view taken substantially on line 3-3 of Fig. 2.

Fig. 4 is a' fragmentary cross-sectional view taken substantially on line 4 4 of Fig. 2.

Fig. 5 is a fragmentary view of the securing lugs on the outside of the wall units.

Fig. 6 is a fragmentary cross-sectional view taken on line 66 of Fig. 2.

Fig. 7 is a fragmentary detailed view partly in section showing the ,co-relation of parts at the lower end of a hopper.

Fig. 8 is a fragmentary sectional view showing a modified form of lining unit.

O11 the drawing l indicates as an entirety a hopper suspended from supporting means, such as girders 2, and having at its lower end a suitable frame' member 3 forming the lower end of the hopper and provided with openings through which ashes collected in the` hopper may be discharged at will. Member 3 is suspended from member 2 in any suitable manner, for example, by spaced uprights 4. Members 2, 3 and 4 thus comprise a. skeleton structure to which may be secured the wall forming units constructed in accordance with my invention. 5 indicates units or plates which cooperate to form a substantially solid or continuous wall and which include means for engagement with other means to. secure the units in position. Preferably these units are composed of substantially rectangular cast iron bodies provided on their outer surfaces with an upstanding flangeor rib 6 along the marginal edges thereof to serve mainly as strengthen ing means.

The units may be secured to spaced uprights 4 by having slotted lugs formed therein adjacent to the uprights which lugs, in the form illustrated, comprise pairs of short substantially parallel .ribs 7 integral with the rib 6 and united at their edges by a web 8 slotted as shown in Figs. 4 and 5 to receive the shank of a bolt, the head of which is retained by the web 8 within the recess formed by the ribs and 7 These lugs are positioned with respectto the uprights 4 so that the bolts 9 may pass through suitable openings in the uprights and thus secure each plate or unit to one or more uprights. Such securing means being formed entirely on the exterior surface of the unit leaves the unit free from holes through which water could flow from the interior of the hopper.

The wall units or plates 5 cooperate to form a substantially solid or continuous wall by reason of the overlapping portions. Each unit is preferably constructed with two over-hanging flanges 10- and two recesses 11 to receive corresponding flanges 10l on adjacent units. Preferably flanges 10 are formed along one vertical side and the bottom edge of a unit and recesses 11 are formed along the upper edge andthe remaining vertical side. By this construction',

acute angle thereto. T ese flan es extend in a horizontal plane or paralle with the upper and lower edges of the units and serve as means for supporting the lire brick lining units-13. Each flange 12 extends outwardlyv from the inner surface of the wall unit referably to a distance slightly less than t e depth of. the refractory lining units, as will be clearly noted by reference to Fig. y3.

Each lining unit 12 is of substantially rectangular cross-section, having at its rear lower longitudinal edge` an included acute angle of substantially the same size as the acute angle between theI upper surface 4of the flange 12 and the inner surface of the unit 5.

The units 13 may vary in length but preferabl are of a size suitable for convenient hand ing. In depth, that is distance from the front or ex osed face to the rear surface or that sur ace adjacent the inner surface of unit 5, is slightly greater than the corresponding length of the flanges 12. The upper surface of each unit 13 is suitably recessed or relieved as at 14 to receive the corresponding flange 12 next above the unit but it will be noticedthat the relief 14 does not extend entirely to the front surface of unit 12 and that accordingly there is a longitudinally extending ridge 15, along the front upper edge of the unit which overlaps the edge of the flange 12 above the unit 13 and lies in close contact with the lining unit supported on each flange thereabove thereby elfectually preventing direct contact with the ange of heated materials or other substance in the hopper which might have a harmful effect on the metal comprising the lianges. If desired, a lining unit 12a 'may be employed having a recess 14 and ridge 15a similar to the corresponding recess 14 and ridge 15 of unit 12 but located on the bottom surface of the unit instead of on the top surface. Ridge 15 would then over-lap the end of the flange 12 which supports the unit as shown in i will be noted that each lining unit 13 is supported on an upwardly extending` flange 12 of the wall unit 5 and will be held in place without any securing means other.

than the flange, even though the wall unit may be inclined with respect to a vertical position to such an extent that the supporting flanges becomesubstantially horizontal. This is due primarily to the cross sectional configuration of the lininfr units 13 and to the spacing apart of the anges and to the length of the flange away from the surface of unit 5. Each unit 13 may obviously be removed from its supporting flange by sliding it outwardly parallel therewith, independently of and without disturbing any other lining unit or any part of the wall section 5, this fact makes renewal of broken lining units particularly inexpensive and simple.

Due to the formation of an acute angle at the lower rear longitudinal edge of the lining unit 13 which fits into the space between the-inner surface of unit 5 and the upper surface of the supporting flange 12 and due also t0 the extension of the supporting flange to a point near the 'outer surface of the lining unit, any tendency for the lining unit to pivot about the outer edge of the supporting flange and thus fall out of place is eifectuall prevented. The rear longitudinal edges o the lining unit would contact respectively with the inner surface of the vunit 5 and the lower surface of the ysupporting flange 12 next above if there should be any tendency for pivoting of the unit 13 about the edge of flange 12. .This action is present also when the wall unit 5 is inclined to the vertical so as to bring the support-ing flange more nearly into a horizontal plane and even when the inclination thereof has become suliicient so that the upper surface of the flange is substantially horizontal the lining yunit 12 will not be dislodged easily nor slide out of place because of their own weight.

Furthermore, it will be obvious that due to the cross-sectional configuration of the lining unit and the size and location of the supporting flange therefor any breakin of the lining units, except possibly the c ip- 4 hopper wall construction since re airs to the wall could be made at more wi ely spaced intervals.

For lining the wall at corners and'between the lowermost supporting flange l2 and members 3 (Fig. 7) mortar, or lining units l2 broken into suitable form and secured in place in any suitable manner may be employed as will be understood' by those skilled in the art.

Although I have described my invention in some detail as embodied in a wall for an ash hopper, I do not desire to limit it to such construction since it is obviously ap- 1 plicable to use wherever it is desired to employ a sectional wall which functions substantially as if continuous, is adapted to prevent leakage of liquid therethrough, is supported exteriorly and capable of supporting lining units.
